Shipping is one of Tumblr’s favorite hobbies, drawing hundreds of millions of engagements each year. On Tumblr, shipping exists in many forms: fan art, fan fiction, manipulated GIFs and videos, and roleplay, just to name a few. It’s a common practice no matter what fandom you’re in—from television shows and movies to K-pop and video games. On Tumblr, the most popular type is slash—ships comprised of two male characters. Out of the top 150, 95 (63%) were guy/guy love.

We grabbed the top 30 ships from 2013—2016. 2013—2015 were ranked by reblogs alone. 2016 and 2017 are ranked by their Trending Score. This includes volume of searches, original posts, and likes in addition to reblogs. We’ve sorted the source content behind each year’s top ships below.

2013

TV | 40%

Music | 40%

Anime | 10%

Celebrities | 6.67%

K-Pop | 3.33%

2013’s most reblogged ships were predominantly slash (76.67%). The remaining 23.33% were all heterosexual (het) ships—there were no femslash ships in the top 30 that year.

The most reblogged ship of the year was from an anime: MakoHaru (Nanase Haruka and Tachibana Makoto, Free! series).
